NOTE:
This User/Service Manual covers software releases up to and including
TARP releases R15.0. The impact of introducing TARP will affect many
areas of this document. Be aware that both TARP and the Lucent Directory
Services (LDS) protocol operations are discussed, and that some
operations and features available in pre-TARP releases will no longer be
applicable in Releases 15.0.
Operations Interworking using TARP
Release 15.0 of the DDM-2000 OC-3 Multiplexer uses Telcordia Technologies’
GR-253 Target ID Address Resolution Protocol (TARP). The Operations
Interworking function provided by TARP offers an alternative to the Lucent
Directory Services protocol (LDS)
*
but will impact operations in a number of ways.
The following synopsis highlights TARP and its impact on network operations:
Why — Lucent Technologies offers TARP for Operations Interworking as a
standard protocol recommended by Telcordia Technologies for TL1 OS
applications to support interworking with other vendor’s equipment (TARP is
supported by multiple vendors).
When — DDM-2000 OC-3 Releases 15.0 use TARP for OI use (transmission
through non-TARP NEs will not be affected). Future releases of DDM-2000
FiberReach (R4.0), FT-2000 (R9.1), and
SLC -2000 (R4.7) will also be TARP
compatible.
Impact — The following items list some of the areas impacted by the
implementation of TARP. For more detailed information refer to the
